A closer look at one example
A clue 6 may occupy a 2×3 rectangle when other clues allow it. Apply the same reasoning to the position in your own round. Choose a deliberate next step.
Watch out for this
No rectangle may contain two clues or overlap another. Take a moment to reassess the position before continuing. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
